The heads are factory Chevrolet Performance pieces for the LS3 engine, CNC ported and polished by LPE. Lingenfelter has tuned the Corvette Grand Sport for 93 octane, and 11.5:1 compression and placed an LPE GT11 hydraulic roller camshaft. Altogether, the 1964 Corvette Grand Sport is good for 550 hp.

Does any of that send chills down your spine? Great, because you can actually buy one of these beasts. Lingenfelter and Superformance will build each as a tailor-made vehicle to the buyer, complete with a two-year/24,000 miles warranty.

Badassery comes with a price, though. Each example runs around $200,000.
